Car manufacturers have stated the importance of developing new fuel technologies ahead of the upcoming Detroit car show.
Three US carmakers- General Motors (GM), Ford and Chrysler - all identified sourcing green energy for cars as a top priority.
"We need to develop alternative sources of propulsion," said General Motors chief Rick Wagon.
A number of manufacturers showed their commitment to green sources of energy with the launch of a number of alternative fuel vehicles at the show, which opens on January 19th.
These included GM's Cadillac Provoq, as well as Honda's CR Z hybrid model, which will cost around £14,000, according to Autocar magazine.
There is also growing interest in green
car insurance policies, with Norwich Union announcing recently that its 'pay-as-you-drive' scheme is proving popular among UK motorists.
Those driving less than 6,000 miles a year could save up to 30 per cent on their
car insurance, a spokesperson said.
Drivers using environmentally-friendly vehicles may be interested in using
InsureandGo's quote engine, which searches over 38 UK providers for the cheapest
car insurance policy.
